Had a similar issue with 2/two networking devices on Ubuntu 12.04 and apt-get wouldn’t resolve any remote host address however, I was able to accept incoming connections. After tons of searching and coming across this post, I had tried the above once before and didn’t seem to work.
Not sure if I had made another change since the first time trying to add the gateway option however, after trying to add the gateway option again I was unable to connect to my Webmin interface, which is assigned/bound to (one ip / one interface), however was able to get apt-get update to resolve domains again and ping remote hosts.
To get Webmin accessible again I removed the gateway option from the network card used for the Webmin interface in the /etc/network/interfaces file.
Not sure if I have some other misconfiguration somewhere else that could be causing that to happen, but for now it works and if I find a better solution I will re-post.
My interfaces file :
# The loopback network interface
auto lo eth1 etho
iface lol inet loopback
# The Primary network interface
iface eth1 inet static
address 192.168.0.3
netmask 255.255.255.0
network 192.168.0.0
gateway 192.168.0.1
dns-nameservers xx.xx.xx.xx xx.xx.xx.xx
iface eth0 inet static
address 192.168.0.4
netmask 255.255.255.0
broadcast 255.255.255.255
network 192.168.0.0
eth1 is for Apache server and is on-board 10/1000 Mb/s eth0 is an add-in card 10/100 Mb/s for local ssh, webmin, etc…
They appear in that order as well.
Thanks!
